About this map

The high Cascades divide at Stampede Pass defines this 1989 topographic study, where the transportation engineering of the late 20th century meets the protected wilderness of the Wenatchee National Forest. This section of the range is a critical corridor for both water and rail, dominated by the massive Keechelus Lake and the infrastructure required to move freight through the mountains. The presence of the Stampede Tunnel and the Whittier (Site) highlights the historical significance of this rail route, which carved through the ridge long before modern interstate developments.

South of the pass, the terrain transitions into the Green River Watershed, a strictly managed area providing water for the City of Tacoma. The map documents a landscape of utility and recreation, from the Crystal Springs Campground along the Yakima River to the technical installations at the Radio Facility and Gaging Station. It is a portrait of a working mountain pass where industrial legacy and environmental conservation occupy the same steep slopes of Amabilis Mountain and Keechelus Ridge.
